Selfish motorists clogging up the hard shoulder following a serious crash on the M5 have left firefighters unable to reach the scene of the accident.

Rescue crews said they were held up in tailbacks attempting to reach the smash involving a biker in Somerset because people are trying to drive the wrong way up the hard shoulder to escape the gridlock.

An air ambulance has landed at the scene following the incident, which completely closed the road in both directions.
